The Genie 117403GT is a genuine OEM Extension Cylinder Extension Tube Assembly designed for the GTH-1048 and GTH-1056 telescopic handler models. Sourced directly from Genie, this assembly meets the exact design intent of the original component, ensuring a correct, direct-fit installation with no guesswork. It is the specified replacement for restoring full telescoping boom function on these telehandlers, and cross-referencing part number 117403GT against your GTH parts manual will confirm applicability to your serial number range.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original engineering drawings, delivering the precise wall thickness, material grade, and surface finish required for hydraulic cylinder service in demanding telehandler applications.
- Direct-Fit Replacement — Engineered to mate with the existing cylinder housing and end fittings on GTH-1048 and GTH-1056 booms, supporting a straightforward swap without reworking hydraulic ports or mounting points.
- Confirmed Fitment for GTH-1048 and GTH-1056 — Verified for Genie's GTH-1048 and GTH-1056 telehandlers, covering a focused range so you can order with confidence for these specific units.
- Full Boom Travel Restored — A worn or damaged extension tube compromises the cylinder's ability to deliver full, consistent boom extension stroke. Replacing it with this assembly restores the rated reach and load-handling capability of the machine.
- Operational Safety Integrity — The extension cylinder is a load-bearing hydraulic component. Maintaining it with a genuine OEM tube assembly helps preserve the structural integrity of the boom system, which is critical for safe material handling at height and distance.
The extension cylinder extension tube is the outer structural sleeve of the telescoping hydraulic cylinder that drives boom extension on Genie GTH telehandlers. As hydraulic pressure acts on the cylinder, the tube guides and supports the inner rod through its full travel, enabling the boom to reach its rated extension length under load. Over time, the tube surface can develop scoring, corrosion, or seal-wear grooves that cause hydraulic fluid bypass, uneven extension, or loss of holding pressure — symptoms that directly reduce the machine's ability to place and hold loads safely. Replacing this assembly with a correctly specified OEM part restores consistent cylinder action and protects the seals and internal components that depend on a sound tube bore.
